Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
truc van » truc va, thuc van, truc ban
van anh » van thanh, tuan anh, van minh
hieu ve » hieu van
hieu va » lieu va, hieu qua
anh vi » hanh vi, anh va, anh ve
su dai » sau dai, si dai, su tai
dai ky » dan ky, dai ly, sai ky
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su dai ky nang x hoi. ((hieu ve) or (hieu va)) cau truc van anh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su dai ky nang x hoi. ((hieu ve) OR (hieu va)) cau truc van anh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su dai ky nang x hoi. ((hieu ve) or (hieu va)) cau truc van anh vi ((cua triet) OR (su triet))*".
